Final answer:
To find the number of calories in a hamburger and a soda, we need more information.
Step-by-step explanation:
To find the number of calories in a hamburger, we can subtract the calories from the sodas from the total calories consumed by each person. Let's start with Kristin:
Number of calories in Kristin's hamburgers: 2053 - (3 sodas * calories per soda)
Solving for Kristin's hamburgers, we get: 2053 - (3 * x) = 5 * x
Similarly, for Jack:
Number of calories in Jack's hamburgers: 1604 - (5 sodas * calories per soda)
Solving for Jack's hamburgers, we get: 1604 - (5 * x) = 2 * x
From these equations, we can solve for the number of calories in a hamburger. Once we have the number of calories in a hamburger, we can find the number of calories in a soda by subtracting the calories in a hamburger from the total calories in a soda.
It is important to note that the information provided in the question lacks the necessary information to calculate the number of calories in a hamburger and a soda.
